ISO 26203的两个部分规定了测试金属板材料以确定应力的方法？高应变率下的应变特性。ISO 26203-1:20 10涵盖了弹性杆型系统的使用。基于实验和数值计算，如耐撞性的有限元分析（FEA）工作，10-3至103 s-1之间的应变率范围被认为与车辆碰撞事件最相关。为了准确评估车辆的耐撞性，在高于10-3 s-1的应变率下对金属材料进行可靠的应力-应变表征至关重要。ISO 26203-1:20 10中的测试方法涵盖了102 s-1以上的应变率范围。
The two parts of ISO 26203 specify methods for testing metallic sheet materials to determine the stress？strain characteristics at high strain rates. ISO 26203-1:2010 covers the use of elastic-bar-type systems.The strain-rate range between 10-3 to 103 s-1 is considered to be the most relevant to vehicle crash events based on experimental and numerical calculations such as the Finite Elemental Analysis (FEA) work for crashworthiness. In order to evaluate the crashworthiness of a vehicle with accuracy, reliable stress-strain characterization of metallic materials at strain rates higher than 10-3 s-1 is essential.The test method in ISO 26203-1:2010 covers the strain-rate range above 102 s-1.
